mod_rewrite returns 302 found

I have an apache 2.2 and I am using mod_rewrite. My objective is to forward traffic from http://localhost:80/AA to http://localhost:8090/BB. So I have a simple rule

RewriteRule http://localhost:80/AA http://localhost:8090/BB

My problem is that the client receives "302 Found". I was hoping that the RewriteRule will forward the traffic from AA to BB and finally the BB will send the response to my client.

Is there a problem with my configuration?

Solution

  • The left side, or pattern, of your RewriteRule should just be the filename you want to match, e.g. ^/AA$. If you also want to make sure the host and port match specific values, you should set up RewriteCond's to match %{HTTP_HOST} and %{SERVER_PORT}. However the latter may be unnecessary unless your web server is configured for multiple domains and ports.

    This is untested, but something like this:

    RewriteCond %{HTTP_HOST}   ^localhost
RewriteCond %{SERVER_PORT} ^80$
RewriteRule ^/AA$          http://localhost:8090/BB

    I would recommend that you try just this first:

    RewriteRule ^/AA$          http://localhost:8090/BB

    and add the RewriteCond's if you need them.

    Edit based on comments: If you are trying to avoid the "302" response, you cannot do that for the situation you describe. When you use mod_rewrite to redirect from one host to another, you will get two responses sent to your browser. The first is 302, which tells the browser to go to the second URL. The second response should be 200.

    With mod_rewrite, you can avoid the redirect in the middle if the rewrite is from one page to another on the same server and port. In that case, the rewrite is internal and the web server can respond with the BB page even though the request is for AA. If you use a different server or port, the web server for AA does not have access to the page BB, so it responds with a redirect to the server that does have access.

    If you can reconfigure your site to use the same port for AA and BB, you can make it work. If not, I think you might be able to do what you want with mod_proxy. I have never used mod_proxy so I am not sure what you would need to do.
